Wonder kid

It all started when Eve was born. She had magical powers (like Wanda and Pietro but before hydra) but that would not be discovered until there parents died. Eve, like Wanda and Pietro was a Maximoff, they had a pretty normal life (that is for living in Sokovia) until the bomb. After this Eve was so sacred she discovered her powers. Wanda and Pietro tried to help her hide them for as long as possible but eventually Hydra found out. Unfortunately hydra took her at the young age of fourteen. Not seeing her siblings until they joined Hydra,

This story goes into them helping Eve hide her power, to her being kidnapped, to them working for Hydra all from Eve's point of view.
